MACHINE FOR MAKING PAPER BLOCKS.

sac et.

To all whom it may concern:

Be it known that I, FRANZ STEPHAN, a subject of the Emperor of Germany,and resident of Untermhaus, near Gera, Principality of Reuss, Germany,have invented certain new and useful Improvements in Machines for MakingPaper Blocks, of which the following is a specification.

It is already known that paper blocks for calendars in slips areproduced in such a manner that several paper-courses lying at firstflatly over each other are made one series of webs which are cut bylengthwisecutters in several parts lying at first beside each otherwhereupon the latter are once more united to one string with correspondingly more layers. If, however, in making calendars in slips a wholecalendar is to be produced by printing, every part of the blockconsisting of a comparatively large number of leaves it becomesimpossible to employ, as customary, for paper-courses running over eachother, the turning headpieces or guide-pulleys turned toward each otherby 90 because in passing the latter the paper-layers are in the firstplace much thicker at the edges than in the middle in as much as theformer have to pass a greater distance and may consequently tear and inthe second place because in both places a dislocation. of the layerstoward each other is takingplace owing to the growing radius ofcurvature in proportion to the increase of. the size of the block whilethe paper is running over the turning-head pieces or the crossedguide-pulleys respectively. lhe dislocation may become so great that itwill be fully impossible to produce calender-blocks by means of thesecontrivances. With this invention, however, cylindrical or conicallybent shovels are employed in order to conduct the paper-courses overeach other whereon the strips lie perfectly even and move with everyfiber in exactly the same direction, so that neither a tearing nor{amutual d1slocat1on of the paper-layers can take place.

The drawing represents such a contrivance in its particulars.

Figures 1 and 2 are views in positions turned toward each other by 90and Figs. 3 and 4 show different layers of the ready made blocks.

In the drawing (Fig. 1) the profile of four rotary-machines A, A A A aregiven in a diagrammatic way and these nmchines are Specification ofLetters Patent.

/ For the sake of a better understanding the rotary machines areprovided with simple broad paperrolls, so that four paper webs runtogether over roller (1. It is possible, however, to use rotary machineswith double or several times broader paper-rolls, in which case themachine would best answer the purpose by being turned at 90 toward theplane of the drawing, and the paper courses cut into two more courses byrotary knives at every single machine and conducted over each other bythe employment of any means used with broad newspaper-rotary-machines,such as turning-bars or funnels while being turned oil at 90, so that,for instance every machine produces with one rotary knife two papercourses. Provided that four machines of double breadth are in operationeight paper courses run over each other on the roller a and are out bythe three rotary knives 7) into four narrow endless strips, so thatthere are situated beside each other four strips of eight paper layerseach. To unite the latter with out difficulty to one single strip thereare arranged four firmly standing shovels cand bent in such a mannerthat their upper ends lie beside each other in one and the same plane,while their lower ends run oif into The four a counter, roller 6. i Inthis connection the registering of the broad paper-webs is ef-- fectedin the same manner as with rotary machines of more rollers. The positionof registering necessary after the cutting into narrow strips is alwaysattained by a measurement of the length of the shovels all of which mustbe changed if the form is changed. A second pair of delivering rollers fserve for the still surer conveyance of thenarrow strong strip nowconsisting, according to the foregoing description, of 2 multipliedby4'. equal to 8 and 8 multiplied by 4 equals 32 layers.

The rotating knife-roller it provided with a number of shearing blades 9thereupon separates while catching in the groovedroller 'i, shortpiecesof the strips gathered which correspond to the length of the blocks.These separated parts of the blocks are brought with known means (cords,catchers or the like) through the band eonveyers 7a tothe laying-drum Zcommon in printing machines and which is provided with catchers m intowhich by means of a dilierence in the rapidity of thetransportation-bands the short paper strips are delivered' There isarranged with this invention in addition to a firmly standingstripping-apparatus n a second stripping- 'contrivancc 0 having anoscillating motion imparted thereto by means of a cam 1 on one side of agear wheel 2, supported on shaft and driven by a pinion 4 on the shaftof the drum Z which engages arm 5 as shown in Fig. 2. a

From the second. contrivanee are stripped oil the parts of thepaper-blocks delivered to the laying drum during a single revolution ofthe drum whereupon it goes np-- Ward or downward, sothat the followingparts of the blocks run a little farther and are detained by the otherstripping-appa ratus n.

The parts of the block stripped off fall on the transportationbands p, grespectively and are so piled upon the latter in the manner given inFig. 3 as to form complete blocks.

lVhile one of the transportathin-bands is receiving the parts of theblock the other multiplicity of layers, a laying drnm, r0

tary knives, means for conducting said layers over each other comprisingconic-ally bent shovels, and means whereby the layers separated bytheknives are again united.
